Title: Picture reader
Inventor: MIYAZAWA HIDEYUKI
IPC: H04N1/407
Filed: 1985-09-09
Abstract: PURPOSE:To read picture information while binarizing correctly the picture information if the background density changes on the same line by setting a threshold level so as to convert digitally the picture signal based on a peak value in the picture signal read by all photodetector arrays. CONSTITUTION:Each picture signal amplified by amplifier circuits 4, 5, 6 is inputted to a peak hold circuit, a peak value is detected from 2 picture signals, correction is applied by shading correction circuits 13, 14, 15 and the result is inputted to A/D conversion circuit 7, 8, 9 as a reference signal. In reading an original whose background density is dense at, e.g., the center, even when the level of a photodetector array 2 of a picture signal 26 is decreased, a peak hold signal 27 is detected from the entire photodetector arrays 1, 2, 3, and since a threshold signal 28 is set based on the value, a correct digital signal 29 is obtained. Thus, even when a black level exists partly on the same line, the density is read correctly.

IPC: H04N1/04
Filed: 1999-07-12
Abstract: PROBLEM TO BE SOLVED: To copy a document that is set in a meandered way as a not meandered document on paper by eliminating the meandered state of the document placed on the paper. SOLUTION: A 1st image memory stores a document PQRS placed with a tilt on paper OABC as 1st image data (bit map data). Coordinates in the X-Y orthogonal coordinate system are given to one-pixel data so that the lower left corner of paper is used for the origin, a left end is coincident with the Y axis and the lower end is coincident with the X axis respectively. In this coordinate system, a tilt angle θ between the left end PS of the document and the Y axis is obtained. Then the X and Y axis are moved in parallel so that the coordinate is converted to have a center O1 of the document PQRS as the origin. Then the coordinates of pixel data configuring the document are rotated by the tilt angle θ around the origin O1. Then the coordinates of the pixel data are restored so that the origin comes to O, and the data are copied on paper.
